The traditional Chinese herbal medicinal material is performed by gas flow, but also has the characteristics of processing non-pollution, maintaining the original chemical properties of the substance, and the characteristics of the powder shape, but can make the Chinese medicine materials have a unique small size effect, surface or interface effect. Wait, thereby exhibiting many excellent properties; the drug will have new advantages such as quantitative, easy to absorb, specificity, targeting when the drug is pulverized to 10 μm to 1 μm. It is more fully able to give full play to the effects of drugs, improve the efficacy, and reduce the economic burden of patients.
Mineral material is absorbed by a large amount of mechanical or thermal energy during pulverization, thereby making the surface of the fresh-ranging ultrafine particles having a relatively high surface energy, and the particles are in extremely unstable state. Particles In order to reduce the surface energy, it is often a steady state through mutual aggregation, and it is easy to cause particles. Therefore, in the processing of the ultrafine powder, the dissolution of dissolution is also an important part, and there are many equipment used for ultrafine powder, and the gas flow pulverizer is one of them. The airflow pulverizer is often used for dry dispersion of agglomerate powder. The advantage is that the particle size reduction rate is high, does not destroy the original topography of particles, and the large particle control is strict.
There is a wide variety of airflow pulverations, and it is also widely used in medium hardness. Its biggest feature is that the output is large, the particle size distribution is narrow, and the product is low in pollution. During the dispersion process, the agglomeration or agglomerate is sent into the dispersion chamber through a helical feeder, and the material is impacted and sheared, and the material is pulverized to reduce the material. The scattered material is delivered to the material collection area by the rising airflow, collected by the cyclone collector and pulse dust collector, and the purified air is discharged from the air blower.
The airflow pulverizer has the following advantages in the preparation of ultrafine powder:
1. Adopt innovative dispersion structure, the unit energy consumption is reduced by 30% compared to traditional discrete.
2, the pulverized replenishing parts use high wear material, wear small wear, long service life.
3, the material can restore its original particle size after depolymerization, and the particle size recovery rate can reach 100%.
4, can be equipped with airflow grading equipment, and the material is different in different fineness of the material during the cancel operation.
6, wide range of applications: can be displaced by hot air to high humidity materials, dry joint operationThe inert gas can be input to dispersion of flammable and explosive materials; can be used to disperse the thermal material or a very low melting material.
7. The system uses negative pressure production, and there is no dust pollution in the production site.
8, intelligent feedback control, simple operation, stable operation.
Airflow pulverizer can be used to calcinate agglomerate, viscous, strong agglomerate powder, such as various metal powder, alloy powder, ultrafine calcined kaolin, water washing kaolin, nanocalic carbonate, flame retardant, barium carbonate, nanoactive Calcium, leaflite, chipperlate sulfate, alumina, aluminum hydroxide, chemical raw materials, dyes, etc.
ALPA Powder Technology has been born in 20 years, and has been adhering to the scientific management model of modern enterprises. He insists on "piety, fine, strict, harmonious" as spiritual concept, and put "pursue excellence, casting dawn brand. , Revitalize the national industry "as the tenet of a strong development.
